So deities which lack this power to hide, their existence is knowable?

It seems likely. I've seen nothing to suggest that anything in nature
is unknowable, so I'd only reserve certainty of unknowability for the
supernatural.

Conjugate variables in Heisenberg's uncertainty principle is the most
obvious counter example. You cannot simultaneously know the momentum and
position of a particle in phase space to arbitrary precision.

Yes, but that's a triviality. Like saying you can't know what's on the
side of sphere that you can't observe. We're really talking about the
knowability of natural law and structure, not "things". It is
Heisenberg's uncertainty principle that informs us. That allows us to
know.
